Abstract: Total energy control(TEC) is a simple and effective design method for controller of flight speed/flight path. This paper proposed a new method based on controlling the amount of aircraft total energy and its distribution. This method adopt several error-feedback loops with simple PI controller to achieve good decoupling effect. Finally, digital simulations of this new control method is conducted with an aircraft on four of its typical situations, and the result validates this method's availability.

Key words: flight control, total energy control(TEC), decoupling control, integrated flight/propulsion control
